Which hydrangea varieties prefer full sun?

Hydrangea paniculata varieties prefer all-day sun in most areas and some afternoon shade in intensely hot-summer areas. They are among the hardiest hydrangeas and excellent for Northern regions. Most bloom in mid-to-late summer with white flowers that often turn pink as they age.

What are the best compact hydrangea varieties for small gardens?

The Seaside Serenade collection offers reblooming hydrangeas bred to stay small, perfect for garden beds and containers. They feature thick stems and flowers that last three months or more on the plant. Examples include Cape Cod, Cape Hatteras, and Cape Lookout varieties, all growing 3-4 feet tall.

Which hydrangeas are best for shade gardens?

Bigleaf Hydrangeas (Hydrangea macrophylla) thrive in part or filtered shade. They offer globe-shaped flower heads in blue, purple, pink, and white depending on soil pH. Reblooming varieties produce flowers all summer and into autumn on current and previous year stems.

What native North American hydrangea types are available?

Oakleaf (H. quercifolia) and Smooth (H. arborescens) hydrangeas are native to Eastern North America. Both prefer shaded or partially shaded sites and feature pure white flowers. Smooth varieties bear round flower clusters while Oakleaf varieties bear cone-shaped clusters.

Can Seaside Serenade hydrangea flowers be dried for arrangements?

Yes, Seaside Serenade hydrangeas are good for drying because their large petal-like bracts are extra-thick. Simply cut the flowers and hang them upside down in a warm, dry place for several weeks to dry.

What are some unique or unusual hydrangea varieties?

Unique varieties include Glacier Bay with white lacecap blooms against dark stems, Double Delights Wedding Gown with pure white double flowers, and Plum Passion Improved with rich purple foliage and pinkish-purple lacecap blooms for zones 7-10.

What companion plants work well with Seaside Serenade hydrangeas?

Good companions include early-spring bloomers like Bleeding Heart and Hellebore, upright plants like Astilbe and Foxglove, foliage plants like Hosta and Coral Bells, and shade-tolerant evergreens such as Hemlock, Rhododendron, and Pieris.

You Want a Hydrangea for Sun

Hydrangea paniculata varieties prefer all-day sun in most areas. They enjoy some afternoon shade in intensely hot-summer areas. Most bloom in mid-to-late summer and continue into early autumn. All have white flowers, though the blossoms on many newer varieties pick up pink tones as they age. If left on the plant in winter, the flower heads fade to a parchment color, adding seasonal interest.
Note: Hydrangea paniculata varieties are among the hardiest of all hydrangeas. This makes them excellent choices for gardeners in the Northern regions.

You Want a Hydrangea Type for Shade

Many gardeners consider Bigleaf Hydrangea (Hydrangea macrophylla) the classic type. These hybrids offer globe-shaped flower heads in shades of blue, purple, pink, and white. In most areas, Bigleaf Hydrangeas thrive in part or filtered shade, especially in the hot hours of the day. Reblooming varieties continue to produce beautiful flowers on and off all summer and into autumn. On current stems and those from the previous year. Varieties that do not rebloom make their flower buds in late summer. They bloom in late spring or early summer of the next year.

Compact Hydrangea Types

The Seaside Serenade® collection is a line of beautiful, reblooming hydrangeas bred to stay small. They are perfect for garden beds and borders, as well as containers. They feature thick stems, leaves, and flowers. This keeps them standing straight even in rainy and windy weather. It prevents them from looking wilted in hot, windy conditions. It also makes them long-lasting cut flowers.

Seaside Serenade® Hydrangea varieties look as beautiful in the landscape as they do when cut for bouquets. Because the large petal-like bracts are extra-thick, individual flower heads can last three months or more on the plant. Most Seaside Serenade® varieties go through a shift in colors as the flowers age, maturing to an antique, parchment-like shade.

The thickness of the bracts also makes these varieties good for drying. The process is simple: Cut the flowers and hang them upside down in a warm, dry place for several weeks.

You Want a Climbing Hydrangea

One species of Hydrangea (H. anomala) breaks the mold. Rather than being a self-supporting shrub, it climbs walls, fences, and other structures. Climbing Hydrangea appreciates a shaded or partly shaded spot and blooms in summer with lacecap-style flowers. While it grows quickly once established, it may take several years to get settled in the landscape. (Sometimes testing a gardener's patience.)

Climbing Hydrangea

A vigorous and showy vine that can climb to 50' or more, clinging to surfaces with aerial rootlets. Slowly grows with a shrubby habit until established, and then takes off with long, fast-growing stems. Lush foliage is covered with magnificent, white lacecap blooms in summer. Stems can reach 50-80' long. Zones 5-9.

Bonus: Hydrangea-like Plants

Schizophragma varieties are often called Chinese Hydrangea or False Hydrangea. They are closely related to Climbing Hydrangea and sometimes confused with it. These plants bear white lacecap-style flowers. Like Climbing Hydrangea, Schizophragma climb by rooting into the structure on which they grow.
